Job Stories From Andover, NJ
Fixing An Unfinished Basement In Andover, NJ

We were able to assist a homeowner in Andover, NJ, after they contacted us dealing with ongoing concerns related to their unfinished basement. The space had began to demonstrate unsightly indications of structural decay, and the owner decided it was time to renovate and ultimately reinforce the area permanently.

In order to resolve these issues they were given an extensive evaluation by our system design specialist Ron, who after surveying the basement was able to conclude the best possible repair strategy. Next our foreman Esau and his crew began installing our specially patented WaterGuard French Drainage System around the perimeter of the room, supplying the area with a clear path for water to directly enter and channel towards their preferred drainage system. Following this, the crew also installed our high-performance TripleSafe Sump Pump System, this powerfully crafted sump pump will provide the basement will much needed protection from heavy water intrusions, with three levels of security against water seepage, the space will continue to remain healthy and dry. To complete the basement finishing repair process, the crew also installed our waterproof ThermalDry Elite Plank Flooring, because they are made out of inorganic materials, ThermalDry planks will stand the test of time in a basement environment, ensuring that mold growth and mildew is a concern of the past. This homeowner was thrilled with their newly transformed and fortified storage space, delivering them complete satisfaction and total peace of mind!

Basement Waterproofing in Hopatcong, NJ

A homeowner living in Hopatcong, NJ became concerned for their basement after noticing water seeping through the floors of their basement. They contacted Quality 1st Basement Systems and scheduled an appointment for an estimate. 

We provided a thorough inspection of the basement and recommended the basement waterproofing system as the best solution. The main components of the basement waterproofing include the WaterGuard French Drain and TripleSafe Sump Pump System. With these systems combined, the basement will stay protected against water intrusion.

A few weeks later, our crew arrived at the home and waterproofed the basement. Since the installation, the homeowner has not experienced any other water issues in their home!

Concrete Sidewalk Repair in Byram Township, NJ

This homeowner in Byram Township, New Jersey noticed their sidewalk was sinking almost 2 inches and cracking. This occurs when concrete is poured over poorly compacted soil. Over time, this soil settles and creates voids in the soil underneath the concrete. If this goes without a repair, this sidewalk will become a tripping hazard, and someone could severely injure themselves.

The homeowner knew this was a problem and they wanted it solved. They contacted Quality 1st Basement Systems and our customer service representative booked them an appointment with our System Design Specialist, Jack Huber. Jack provided a thorough inspection of the sidewalk and suggested they use polyurethane foam to lift and level the concrete. 

A few days later, our foreman Ramon Romero arrived at the job site and began installing the PolyLevel Injection System. This is done by drilling small, penny-sized holes into the concrete and injecting the polylevel into the soil underneath the concrete. This process is repeated until the slab is brought to a level position. PolyLevel is a lightweight and environmentally friendly solution that will not add weight to the existing soil. This is the best solution to repair sinking concrete.

Within 20 minutes the concrete was brought to a level position and the homeowner was happy with the results. They were able to safely walk on their sidewalk without worrying about tripping.
